Part a - question 1) what can be inferred about the harappan culture? a) the harappan culture was uncivilized compared to the other cultures of that time. b) the harappan culture was the best culture of the time period. c) the harappan culture was unimportant. d) the harappan culture was very complex. question 2) selct the sentence from the text which best supports your answer in part a. a) " they fortified their city walls and fashioned bronze and stone weapons." b) " included among the first great river valley civilizations, the harappans settled about 5,000 years ago in the area around the indus river. " c) " a few texts discovered in the ruins of harappan cities and from other cultures make little mention of how the civilizations collapsed." d) " they built a water plumbing system, hospitals, public baths, and dams to control flooding."

answer:

d

explanation:

d) " they built a water plumbing system, hospitals, public baths, and dams to control flooding." ​

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

always metal! releases anger and stress! bands i suggest are trivium, lamb of god, slayer, and amon amarth
